Back to Products page

The set of Straps with Door Hooks adds an optional attachment method of the RoofBag car top carrier to a car without a rack.

Order these straps to install any RoofBag car top carrier on a car without a roof rack, instead of using the Pass-Through Straps that are shipped standard with each Roofbag carrier. (The Pass-Through Straps are installed through the inside of the car following the headliner and take up 1 to 2 inches of overhead space. In some cars, this reduction in overhead space may interfere with the head of tall drivers).

Each strap consists of 3 sections: a Hook Short Strap, a Top Strap, and a Hook Long Strap. The Hook Short Strap fastens to the door frame ridge on one side. The Top Strap goes over the top of the RoofBag car top carrier. The Hook Long Strap fastens to the door frame ridge on the opposite side of the car. The three sections are joined by 2 heavy-duty side-release buckles.

Straps are heavy-duty, 1.5 inches wide, seat-belt style. They are soft, flexible and easy to work with, and have been specially treated to be water-repellent while retaining their softness.

Door hooks are made of vinyl-coated steel, and they don't damage the car's finish.

4 side-release buckles (2 on each strap) allow easy connect-disconnect and quick access to the contents of the car top carrier.

Total length of Hook Short Strap + Top Strap + Hook Long Strap: 92 inches.

Finger loops at the ends make it easy to tighten the straps.

Straps are water-repellent -- they don't get wet and they don't wick water into the car.


IMPORTANT: To use these straps with door hooks, your car must have a rigid ridge or lip, about 1/2" high and 1/2" wide, sticking downward from the upper section of the door frame and running front to back. This ridge may be covered with a removable rubber seal or plastic molding (see detail pictures above).

If the car doesn't have this ridge, use instead the Pass-Through Straps that came with the carrier, which work on any car without a rack.

Once installed and the doors are closed, the Door Hooks must pass two tests:

1- The hooks must not be visible from the outside of the car.
2- The hooks must remain attached to the door frame ridge.

If the hooks don't pass these two tests, the car probably does not have the proper ridge and we don't recommend using these straps. They may not hold the carrier securely. Use instead the Pass-Through Straps that came with the carrier, which work on any car without a rack.

When properly installed, the Straps with Door Hooks fasten your car top carrier to the car's frame securely.


The Top Strap slides under the strap guides at the top of the carrier.

With front door open, fasten the straps with hooks to a hard ridge or lip approximately 1/2" wide by 1/2" high sticking down from the top of the door frame. The ridge may be covered with a plastic molding or rubber seal. Close the door over the strap. The strap should exit between the door and the frame, and the hook should be invisible from the outside.

Slide the half buckles of the Hook Straps into the half buckles of the Top Strap until they click. Repeat for the rear straps. NOTE: If your car does not seem to have the required 1/2" ridge, use the Inside Straps that come with the carrier instead. Click for installation details.

The length of the each strap is adjustable at each of the two buckles. To adjust, pull from the Finger Loops located at each end of each strap.

Secure the free ends of the straps by wrapping the free end around the taut section of the strap and tucking the end under the last turn. This avoids flapping of the free end during travel (see diagram above).

If a strap makes a whistling or a rumbling noise during travel, unbuckle the suspect taut section of strap, twist it half a turn or one full turn and re-buckle.


•  Fasten RoofBag carrier to door frame, if car has a ” solid ridge inside door frame.
•  Adds an optional fastening method if Pass-Through straps interfere with driver's head.
•  Four side-release buckles provide easy access to carrier's contents.
•  Water-repellent straps avoid water wicking inside the car.
